While Call of Duty: Black Ops 6's Zombies mode returns to its round-based format, that doesn't mean it's a complete remake without any new features.

BO6 Zombies introduces two new maps at launch, a new Field Upgrade, GobbleGums make their return from Black Ops 3, and there’s even a new damage type that even has its own Ammo Mod. That’s right, there are more new ways to take on the undead hordes than ever before.

The four classic Ammo Mods are back, but this fifth one is different and more interesting than most. On Zombies’ two new maps, Terminus and Shadow Falls, you’ll need all the help you can get when dealing with the hordes that come your way.

Here's everything we know about the new damage type and ammo mod in Black Ops 6 Zombies.
